Day One is a personal journaling app available for Android, macOS and iOS devices. Some features include: data syncing with multiple devices; end-to-end encryption, Markdown authoring of entries; location, weather, date, time, and other automatic metadata; quick entry menu bar (Mac only); and reminders.[1]
The application has been reviewed by Macworld,[2] The Verge,[3] Lifehacker[4] and other tech websites. The Mac version of Day One was chosen as "Mac App of the Year" in 2012 by the Mac App Store[5] and won an Apple Design Award in 2014 for being "super well-designed on OS X and being exactly what it needs to be and nothing more."[6]
Day One was acquired by Automattic, the owner of WordPress.com, on June 14, 2021.[7]
Day One had a service called Publish for publishing selected entries to a Day One-hosted webpage and sharing via Facebook, Twitter, Tumblr, and other social services.[8]
On February 4, 2016, the developers, Bloom Built, introduced Day One 2 for Mac and iOS, citing the release as a full app rebuild. The update introduced a visual overhaul and new features such as multiple journals and photos.[9]
On June 12, 2017, Bloom Built added end-to-end encryption to Day One 2 after two years of development. The update was a culmination of the Day One Sync services launched in 2015 as a replacement for iCloud and DropBox sync.[10]
